In the US, Phragmites australis ssp. australis (European Common Reed) generally is considered to be a harmful invasive species whose dense monoculture stands greatly reduce species diversity. I examined the effectiveness of 3 control measures in discrete stands of European Common Reed along the perimeter of a small urban New England saltmarsh. Cutting, cutting plus application of an herbicide, and increasing salinity via excavation to reduce elevation along with ditching to enhance tidal flow into the marsh, were compared. I measured culm heights as a measure of plant vigor over a period of 15 years. Three years of cutting culms, with or without treatment with the organic herbicide Burn-Out II^®, was not a successful control. The only moderately successful control (2–26% reduction in height) involved increased inundation with seawater, which increased salinity by 33%. Any excavation of a European Common Reed stand should include precautions to avoid establishing a new stand in the spoils dewatering area.
